“…Next, the solution containing beaker was performed by ultrasonication 1 h under ambient conditions and placed in air at room temperature for 12 h in order to grow ZnO-MWCNTs composite. Finally, the products was collected by centrifugation and washed with distilled water and ethanol, then dried at 60 • C in vacuum for 6 h. Then ZnO-MWCNTs films were formed [25][26][27].…”

The perforated ZnO nanoflakes with high degree of crystallinity and uniformity were synthesized via the hydrothermal-assisted sol-gel technique without any template. ZnCl 2 was used as a Zn-containing precursor, causing the oriented growth of particles. The observation of a hole on the facet of the as-synthesized particles was discussed in this work. XRD, TEM, and DRS were used to investigate the prepared powder and a simple mechanism was suggested to explain the hole formation on the surface of nanoflakes. As a result, the synthesized powder included pure ZnO with direct band gap energy of 3.24 eV. The range of particle size was within 1 lm in diameter and \50 nm in thickness. A circle hole with 300-500 nm in diameter was observed on the facet of the as-synthesized particles.
